And the Pride Park manager has got his feelers out to find another - who he feels could be the last piece of the jigsaw.
"I am looking for another wide player," he told the club's official website.
"Someone who can give us a bit of pace and a trick.
"We are still looking to improve all areas of the squad."
The Derby manager warned that there could also be casualties in order to bring in new faces.
He added: "There might be some people who leave to enable some more to come in."
